Real Estate Investor Tax Guide 2026: What the One Big Beautiful Bill Changed and What You Should Do About It

The One Big Beautiful Bill Act — signed July 4, 2025 — is the most significant tax law for real estate investors since 2017. If you own rental property, flip houses, or invest in commercial real estate, nearly every tool in your tax toolkit just got upgraded, made permanent, or both.

This guide covers every OBBBA provision that affects real estate investors, with the dollar-specific examples and Indiana angles you won't find in a national summary. If you already read our blog post on turning rental property losses into a tax advantage, this picks up where that one left off.

100% Bonus Depreciation Is Back — Permanently

This is the headline change. Under the old rules, bonus depreciation was scheduled to drop to 20% in 2026 and disappear entirely in 2027. The OBBBA reversed the entire phasedown and made 100% bonus depreciation permanent for qualified property acquired after January 19, 2025.

What this means in practice: if you buy a $1 million rental property and a cost segregation study reclassifies $300,000 of that purchase price from 27.5-year building components to 5-, 7-, and 15-year personal property and land improvements, you can deduct the entire $300,000 in year one. Under the old phase-down schedule, that same study would have only generated a $60,000 first-year deduction (20% of $300,000) in 2026.

There's one critical timing trap you need to know. Property acquired under a written binding contract entered into before January 20, 2025 remains subject to the old phase-down rates — even if you didn't place it in service until 2026. The IRS confirmed this in Notice 2026-11. If you closed on a property in late 2024 or early January 2025, the contract date determines your bonus rate, not the closing date. This distinction could mean the difference between a $300,000 deduction and a $60,000 deduction on the same property.

Another change worth noting: there are no more placed-in-service deadlines. Under the old rules, property generally had to be placed in service by 2027 to qualify. That deadline is gone. A property acquired after January 19, 2025 qualifies for 100% bonus depreciation whenever it's placed in service — next year, five years from now, or twenty years from now.

If you already have rental properties and haven't done a cost segregation study, this is the time. The combination of permanent 100% bonus depreciation and cost segregation can generate massive first-year deductions. See our blog post on depreciation and cost segregation for the full mechanics — but the short version is this: every dollar reclassified from the 27.5-year building to a shorter-lived component is now 100% deductible in year one, permanently.

The 20% QBI Deduction Is Now Permanent

Rental property income generally qualifies for the 20% Qualified Business Income deduction under Section 199A — meaning you can deduct 20% of your net rental income before calculating your tax. This deduction was scheduled to expire after 2025. The OBBBA made it permanent.

For a rental owner with $100,000 in net rental income, the QBI deduction saves roughly $4,400 to $7,400 in federal tax depending on your bracket (20% × $100,000 = $20,000 deduction, taxed at your marginal rate).

The OBBBA also expanded the phase-in ranges for the QBI limitation. Previously, if your taxable income exceeded $394,600 (married filing jointly) and your rental activity didn't meet the safe-harbor or W-2 wage tests, the deduction could be limited or eliminated. The new phase-in range is now $150,000 above the threshold (up from $100,000 for MFJ), giving more taxpayers in the gray zone access to at least a partial deduction.

If you're a landlord who hasn't been tracking hours spent on rental activities, start now. The IRS safe harbor for the QBI deduction (established by Revenue Procedure 2019-38, not by the OBBBA itself) requires 250 hours of rental services per year, with contemporaneous records. The OBBBA's permanence of the QBI deduction simply means this safe harbor is now relevant indefinitely. Maintaining a simple time log could be worth $4,000–$7,000 per year in tax savings.

1031 Exchanges Survived — Use Them

Despite years of proposals to limit or eliminate them, Section 1031 like-kind exchanges came through the OBBBA completely untouched. The Biden administration's budget proposals (2022–2025) had repeatedly called for capping 1031 deferrals at $500,000, but none of those restrictions were included in the OBBBA.

This means you can still sell a rental property, reinvest in a replacement property within the required timeline, and defer the entire capital gains tax — no dollar cap, no income limit, no restriction on how many times you do it.

The 1031 exchange is the backbone of the real estate wealth-building playbook we describe in our newsletters. Here's the strategy in a nutshell: buy your first rental property. When it appreciates, use a 1031 exchange to trade up into a larger property. Repeat. By the time you pass away, the property gets a stepped-up basis to fair market value, and the decades of deferred gains could potentially disappear entirely.

The OBBBA made this strategy even more powerful because the estate tax exemption is now $15 million per person ($30 million for a married couple) — meaning most real estate portfolios will pass to heirs completely free of federal estate tax, with the stepped-up basis wiping out all the deferred gains. We'll cover this more in the estate planning section below.

The practical rules haven't changed: you have 45 days to identify replacement properties and 180 days to close. You must use a qualified intermediary — you cannot touch the proceeds. Talk to us before you sell any investment property so we can help you evaluate whether a 1031 exchange makes sense.

The $15 Million Estate Exemption Changes Everything for Real Estate Families

The federal estate tax exemption was $13.99 million per person in 2025, but it was scheduled to drop back to roughly $7 million in 2026 when the TCJA provisions expired. The OBBBA made the exemption permanent at $15 million per person ($30 million for married couples), indexed for inflation starting in 2027.

For real estate investors, this is the second half of the buy-exchange-die strategy. Because the stepped-up basis at death is preserved, your heirs receive your properties at current fair market value — not your original cost basis. All the gains you deferred through 1031 exchanges over your lifetime? Gone. And with a $30 million exemption for a married couple, the estate tax itself is unlikely to apply to most real estate portfolios.

Assume you bought your first rental property for $50,000 thirty years ago. Through a series of 1031 exchanges over the decades, you now own a portfolio worth $3 million. Your cumulative deferred gain is roughly $2.5 million. If you sold during your lifetime, you'd owe roughly $500,000+ in federal tax. But if you hold the properties until death, your heirs inherit them at the $3 million fair market value — and the $2.5 million of deferred gains vanishes. With the $15 million per-person exemption, no estate tax is owed either.

SALT Cap

Several other OBBBA provisions affect real estate investors. Here are the ones worth knowing.

The SALT cap increased from $10,000 to $40,000 for 2025, rising by 1% per year through 2029 ($40,400 in 2026, $40,804 in 2027, and so on) — then reverts to $10,000 in 2030. The cap phases down for taxpayers with MAGI above $500,000 for 2025 ($505,000 for 2026), reducing by 30 cents for every dollar over the threshold, with a floor of $10,000. This helps investors who itemize and pay substantial state and local taxes. But here's the detail most summaries miss: business property taxes reported on Schedule E (rental property) are not subject to the SALT cap at all. They remain fully deductible as a business expense. The SALT cap only applies to property taxes claimed as an itemized deduction on Schedule A — typically your personal residence.

Opportunity Zones 2.0: A Renewed Program

The Qualified Opportunity Zone program was set to expire for new investments after December 31, 2026. The OBBBA made it permanent and restructured it with rolling ten-year designations. Governors will designate new zones by July 1, 2026, effective January 1, 2027. The new program includes enhanced rural incentives and expanded reporting requirements.

For investors with capital gains to defer, the renewed program offers a five-year deferral with a 10% basis step-up for gains invested after December 31, 2026. If you're sitting on a significant gain from a property sale and aren't using a 1031 exchange, the Opportunity Zone program may be worth exploring as an alternative deferral strategy. Ask us for the latest on Indiana-designated zones.

Indiana-Specific Considerations

Indiana real estate investors enjoy several advantages that compound with the federal OBBBA changes.

Indiana's flat state income tax rate is now 2.95% for 2026, reduced from 3.00% in 2025. Combined with county income taxes (ranging from about 1% to 3.4% depending on your county — Hamilton County is currently 1.1%), Indiana's total state and local income tax burden remains among the lowest in the Midwest.

Indiana's property tax cap system limits property taxes to 1% of assessed value for homesteads, 2% for other residential property (including most rentals), and 3% for commercial property. This cap provides predictability for rental property investors that many other states don't offer.

The Indiana PTET (Pass-Through Entity Tax) election remains available for partnerships and S-Corps. By electing to pay Indiana state income tax at the entity level, you create a federal deduction for the state tax payment that isn't subject to the SALT cap. With the SALT cap now at $40,000, the PTET advantage has narrowed — but for higher-income investors, it may still save federal tax. This requires annual analysis.

Indiana does not impose a separate state capital gains tax rate — all income, including capital gains, is taxed at the flat 2.95% rate. This is a meaningful advantage when selling appreciated property compared to states like California (13.3%) or New York (up to 10.9%).

Your Mid-2026 Action Checklist

If you own rental or investment real estate, here are the moves to consider right now.

Get a cost segregation study on any property acquired after January 19, 2025. With permanent 100% bonus depreciation, every dollar reclassified from the building to shorter-lived components is deductible in year one. The study typically costs $5,000–$15,000 and can generate deductions of $100,000+ on a single property. Ask us for a referral.

Review your 1031 exchange options before listing any property for sale. If you're planning to sell a rental this spring or summer, a 1031 exchange could defer the entire capital gains tax. The 45-day identification window and 180-day closing window require advance planning. Don't list a property without talking to us first.

Check the acquisition date on any property purchased in late 2024 or early 2025. If the binding contract was signed before January 20, 2025, the property qualifies for only 40% bonus depreciation if placed in service in 2025, or 20% if placed in service in 2026 — not 100%. This affects both the depreciation you've already claimed and any cost segregation study you're planning.

Adjust your 2026 estimated tax payments. If you're taking large bonus depreciation or cost segregation deductions in 2026, your estimated taxes may be significantly lower than 2025. Overpaying estimated taxes ties up cash unnecessarily. We can help recalculate.

Start tracking your rental activity hours if you want to claim the QBI deduction. The 250-hour safe harbor requires a contemporaneous log — a spreadsheet or app recording dates, hours, and activities. Starting mid-year is better than not starting at all.

Evaluate whether the Indiana PTET election still saves you federal tax under the new $40,000 SALT cap. The math changed. We should run the numbers for your specific situation.

Strategies Indiana Real Estate Investors Should Know

Strategy 1: Buy, cost-segregate, and deduct in year one. Assume you purchase a $500,000 rental property in 2026. A cost segregation study reclassifies $150,000 from the building to 5-, 7-, and 15-year property. With permanent 100% bonus depreciation, you deduct $150,000 in year one — in addition to normal depreciation on the remaining building. If you're in the 24% bracket, that's $36,000 of immediate federal tax savings on a property that may be generating positive cash flow. The property can show a tax loss while producing real income. Ask us how this applies to your particular situation.

Strategy 2: The buy-exchange-die playbook. Buy your first investment property for $200,000. When it's worth $350,000, do a 1031 exchange into a $500,000 property. When that one is worth $700,000, exchange again into a $1 million property. You've never paid a dollar of capital gains tax along the way. With the OBBBA's $15 million estate exemption and preserved stepped-up basis, your heirs inherit the property at fair market value — the accumulated gains disappear, and there's no estate tax either. This is the single most powerful wealth-building strategy available to real estate investors, and the OBBBA just made it stronger. Ask us how to structure this for your portfolio.

Strategy 3: Convert your short-term rental to unlock passive losses. If you own a rental property that's generating a paper loss (often from cost segregation and bonus depreciation) but you can't deduct the loss because your AGI exceeds $150,000 (the $25,000 rental loss allowance phases out completely at that level), consider converting it to a short-term rental with an average guest stay of 7 days or less. If you materially participate in the short-term rental (which means you spend more time on it than anyone else), the loss is no longer passive — it can offset your wages, business income, and other ordinary income.

We've helped several clients use this strategy to save tens of thousands in taxes. See our blog post on rental property losses for the full details, and ask us how the restored 100% bonus depreciation magnifies this approach.

What You Should Do Now

1. If you bought rental or investment property after January 19, 2025, call us to discuss a cost segregation study. The math has changed dramatically with permanent 100% bonus depreciation.

2. If you're planning to sell any investment property in 2026, talk to us before you list it. A 1031 exchange can defer the entire gain, and the buy-exchange-die strategy is more powerful than ever.

3. If you have rental income, start a 250-hour activity log now to protect your QBI deduction.

4. If you're an Indiana investor, let us run the PTET analysis under the new $40,000 SALT cap to see if the election still benefits you.

The OBBBA rewrote the rules in your favor. The question isn't whether these changes benefit real estate investors — they clearly do. The question is whether you're structured to capture every dollar of savings available to you. If you'd like help figuring that out, call us at 317.867.5427.
